I am new here so someone may have addressed this but I haven’t seen it yet. I bought a 2015 Ram eco diesel last year and love this truck. Problem is the glow light came on and was flashing read the code it was a bad glow plug in #3 cylinder my son and I have a mechanical back ground we got the plug unthreaded all is good but the plug will only come up a little I believe it swollen we have tried everything we can think of to get out has anyone had this happen if so how did you get it out?

This situation is a nightmare. We removed one on our truck, by spraying with penetrating lube and unscrewing 2-3 threads per year. After a week of repeated lubing and working the glow plug in and out, we finally got it out all the way. However, many shops and dealers snap off the glow plug and the head has to be removed. The glow plugs do not have anti-seize on them from the factory...big mistake.
